This study shows metformin acts as a bacterial chemorepellent, reducing bacterial penetration into mucus by altering motility and chemotaxis.

This study shows that IgA-mediated bacterial aggregation at weaning prevents mucus penetration by commensal bacteria, while its disruption allows deeper bacterial encroachment.

The paper develops IMscore and IMGindex to assess gut microbiota-immune interactions and identify aberrant microbe-immune responses in early Multiple Sclerosis.
